Mit einem aufsehäumbaren Kunststoff thermisch Isoliertest koaxiales Rohrsystem Thermally insulated t coaxial pipe system with a foamable plastic
Es ist zuweilen notwendig, flüssige oder gasförmige Medien erwärmt oder gekühlt in Rohrleitungen zu transportieren. ä It is sometimes necessary to heat or cool liquid or gaseous media in pipelines. Ä
Für den Transport gekühlter Medien ist beispielsweise ein Rohrleitungssystem bekannt, bei dem konzentrisch zum Innenrohr, das das zu transportierende Gut führt, ein Rohr mit größerem Durchmesser angeordnet und der Zwischenraum zwischen den beiden Rohren mit einem Kühlmittel gefüllt ist. Damit das Innenrohr zu dem Außenrohr stets seine Lage beibehält, sind zwischen beiden Rohren Abstandshalter angebracht.For the transport of cooled media, for example, a pipeline system is known in which concentrically to the inner pipe, that guides the goods to be transported, a tube with a larger diameter is arranged and the space between the two tubes is filled with a coolant. So that the inner tube always maintains its position relative to the outer tube Spacers attached between the two tubes.
Es ist auch eine Zusatzheizung für glatte Metallrohre bekannt, bei der ein Heizleiter achsparallel oder wendelförmig auf dem zu beheizenden Rohr angeordnet ist, der dann mit einer Folie oder einem Mantel, die um das Rohr und dem Heizleiter gewickelt sind, auf dem Metallrohr festgehalten wird. Der Nachteil dieser " Rohre ist, daß sie nicht flexibel und somit schlecht transportabel sind. Bekannt ist auch eine Anordnung, bei der der elektrische Heizleiter in den Wellentälern eines gewellten Metallschlauches angeordnet ist.Additional heating for smooth metal pipes is also known, in which a heating conductor is arranged axially parallel or helically on the pipe to be heated, which is then covered with a film or a jacket wrapped around the pipe and the heating conductor are held on the metal pipe. The disadvantage of these "pipes" is that they are not flexible and therefore difficult to transport are. An arrangement is also known in which the electrical heating conductor is in the wave troughs of a corrugated metal hose is arranged.
Die Erfindung geht zur Lösung des Problems der Beheizung oder Kühlung von in einem Rohrsystem transportierten flüssigen oder gasförmigen Medien einen anderen Weg.The invention takes a different approach to solving the problem of heating or cooling of liquid or gaseous media transported in a pipe system.
Gemäß der Erfindung ist um das oder die Leitungsrohre ein dae Heiz·» oder Kühlmittel führendes elliptisch geformtes Rohr According to the invention, around the line pipe or pipes there is an elliptically shaped pipe carrying the heating or cooling medium
angeordnet. Das hat den Vorteil, daß jetzt ein flüasigesarranged. This has the advantage that it is now a liquid

oder, gasförmiges Heiz- oder Kühlmittel in dem Zwischenraum zwischen dem kreisförmigen Leitungsrohr und dem elliptisch geformten Rohr fließen kann, das Leitungsrohr also praktisch allseitig umströmt wird, so daß gute Wärmeübertragung in beiden Richtungen gewährleistet ist. Ein weiterer Vorteil ist es, daß auf Abstandshalter verzichtet werden kann, da der Außendurchmesser des Leitungsrohres gleich oder zumindest annähernd gleich der kleinen Achse des elliptisch geformten Rohres ist. Zweckmäßig wird man das elliptisch geformte Rohr sowie das oder die Innenrohre und das Außenrohr mit einer schraubenlinienformigen Wellung versehen und somit das ganze Leitungssystem flexibel gestalten. Vorteilhaft wird man das elliptisch geformte Rohr aus einem Metall, vorzugweise aus Kupfer, herstellen. Kupfer ist besonders geeignet, weil es sehr korrosionsbeständig ist* In einigen Fällen hat es sich als zweckmäßig erwiesen, einen Kunststoff, beispielsweise auf der Basis Polytetrafluoräthylen, zu verwenden» Kunststoffe auf dieser Basis zweichnen sich durch eine hohe Beständigkeit gegen die meisten Stoffe aus. Ein weiterer Vorteil dieser Kunststoffe ist ihre große Hitzebeständigkeit, so daß sie sich vorzüglich für Heizzwecke eignen. Zur Erhöhung der mechanischen Festigkeit wird man sie mit einer metallischen Bewehrung versehen.or, gaseous heating or cooling medium in the space can flow between the circular conduit pipe and the elliptically shaped pipe, so the conduit pipe is practical is flowed around on all sides, so that good heat transfer is guaranteed in both directions. Another benefit is it is that spacers can be dispensed with, since the outer diameter of the conduit pipe is the same or at least is approximately equal to the minor axis of the elliptically shaped tube. The elliptically shaped tube is expedient as well as the inner tube or tubes and the outer tube provided with a helical corrugation and thus the whole Design the pipe system flexibly. The elliptically shaped tube is advantageously made from a metal, preferably from Copper. Copper is particularly suitable because it is very resistant to corrosion * In some cases it has proved to be expedient to use a plastic, for example based on polytetrafluoroethylene »plastics on this basis, they are distinguished by their high resistance to most substances. Another advantage of these plastics is their great heat resistance, so that they are eminently suitable for heating purposes. To increase the mechanical strength, they will be provided with metallic reinforcement.
Ein solches metallisches elliptisch geformtes Rohr -besteht aus einem längseinlaufenden, zu einem Rohr geformten, verschweißten, gegebenenfalls gewellten und anschließend elliptisch verformten Metallband. Such a metallic elliptically shaped tube consists of a longitudinally running metal strip shaped into a tube, welded, optionally corrugated and then elliptically deformed .
Zur näheren Erläuterung der Erfindung ist in der Figur ein Anwendungsbdispiel näher beschrieben. Dais zu kühlende oder zu erwärmende Material 1 wird in dem inneren gewellten Leitungsrohr 2 transportiert, In dem Zwischenraum zwischen dem inneren Leitungsrohr 2 und dem elliptisch geformten Rohr 3» das gegebenenfalls auch mit einer schraubenlinienföriaigen VTellung versehen ist, befindet sich das Heiz« bäßvr. Kühlmittel 4. DasTo explain the invention in more detail, an application example is described in more detail in the figure. The material 1 to be cooled or heated is transported in the inner corrugated pipe 2. In the space between the inner pipe 2 and the elliptically shaped pipe 3, which may also be provided with a helical pitch, is the heater. Coolant 4. That

innere Leitungsrohr 2 wird durch die elliptische Form des Rohres 3 *η seiner Lage festgehalten. Zur äußeren thermischen Isolierung ist das elliptisch geformte Rohr 3 von einem aufschäumbaren Kunststoff 5» vorzugsweise Polyurethan, umgeben. Zum Schutz gegen mechanische Beschädigungen wird diese Isolierung aus aufschäumbarem Kunststoff 5 von einem gewellten Metallmantel 6 umgeben. Zum Schutz dieses Metallmantels 6 gegen Korrosion wird auf diesen eine Schicht Polyäthylen 7 gespritzt.inner pipe 2 is held in place by the elliptical shape of the pipe 3 * η . For external thermal insulation, the elliptically shaped tube 3 is surrounded by a foamable plastic 5, preferably polyurethane. To protect against mechanical damage, this insulation made of foamable plastic 5 is surrounded by a corrugated metal jacket 6. To protect this metal jacket 6 against corrosion, a layer of polyethylene 7 is sprayed onto it.
In Weiterführung des Erfindungsgedarikens kann das metallische innere Leitungsrohr 2, das beispielsweise aus Kupfer hergestellt ist, auch als supraleitender Hohlleiter verwendet werden. Hierzu muß aber ein Kontakt zwischen dem inneren Leitungsrohr 2 und dem elliptisch geformten Rohr 3 durch eine Isolierschicht 8 verhindert werden. Der Zwischenraum zwischen Innenrohr 2 und elliptisch verformten Rohr 3 wird in diesem Fall mit einem Kühlmittel k gefüllt, das möglichst tiefe Temperaturen zuläßt, beispielsweise flüssiges Helium.In a continuation of the inventive concept, the metallic inner conduit 2, which is made for example from copper, can also be used as a superconducting waveguide. For this purpose, however, contact between the inner conduit pipe 2 and the elliptically shaped pipe 3 must be prevented by an insulating layer 8. The space between the inner tube 2 and the elliptically deformed tube 3 is in this case filled with a coolant k which allows temperatures as low as possible, for example liquid helium.
